Orangutan's Vocal Feats Hint At Deeper Roots of Human Speech

Tuesday, March 14, 2017

Rocky wowed scientists when he showed he could control his vocal cords much the way people do. His abilities suggest that early humans might have spoken words 10 million years ago.


Scientists May Have Solved The Mystery Of Nodding Syndrome

Wednesday, February 15, 2017

For decades, scientists suspected that the parasite responsible for river blindness might be causing a rare form of epilepsy. Now they have evidence.


A Brain Tweak Lets Mice Abstain From Cocaine

Monday, February 13, 2017

Scientists have created addiction-resistant mice by altering the reward system in their brains. The findings shed light on the biochemistry of addiction.


Art Exhibition Celebrates Drawings By The Founder Of Modern Neuroscience

Thursday, January 26, 2017

Santiago Ramón y Cajal's drawings of nerve cells changed scientists' understanding of the brain. Now, 80 of those drawings are going on display at an art museum in Minnesota.


Politics Aside, Counting Crowds Is Tricky

Monday, January 23, 2017

Claims about the size of crowds for both President Trump's inauguration and the protests that followed the day after, are being debated. Scientists struggle with how to do that kind of head count.


Flipping A Switch In The Brain Turns Lab Rodents Into Killer Mice

Thursday, January 12, 2017

When scientists activate hunting circuits in the brains of genetically modified mice, the animals attack insects and even bottle caps as prey. It gives clues to the evolution of hunting in humans.


Brain Area That Recognizes Faces Gets Busier And Better In Young Adults

Thursday, January 05, 2017

From birth through age 30 or so, our ability to recognize faces keeps improving, research shows. At first, kids discern adult faces better than other kids' mugs. Not so after adolescence.


As Sleep Improves, So Does An Injured Brain

Wednesday, December 21, 2016

After a serious brain injury, people often sleep just a few minutes at a time. As the brain heals, sleep patterns begin to return to normal. The link suggests restoring sleep could improve recovery.


Pentagon Shelves Blast Gauges Meant To Detect Battlefield Brain Injuries

Tuesday, December 20, 2016

The military hoped the body-worn sensors would identify troops with brain injuries from a bomb blast. Instead, the sensors showed service members may be at risk from firing their own weapons.


Zap! Magnet Study Offers Fresh Insights Into How Memory Works

Thursday, December 01, 2016

A magnetic pulse to a certain spot in the brain of healthy volunteers restored recently "forgotten" thoughts, researchers found. The study is shifting the understanding of short-term recall.


Glowing Human Cells May Shed Light On Sickness And Health

Wednesday, November 30, 2016

Researchers who developed a collection of human stem cells with glowing internal structures have begun sharing them with colleagues. The glow reveals the secret workings of cells.


Your Dog Remembers Every Move You Make

Wednesday, November 23, 2016

Our canine pals remember lots of facts, like where to find the food bowl. Now there's evidence they also have aspects of "episodic memory," which allow them to relive experiences and events.


Heavy Screen Time Rewires Young Brains, For Better And Worse

Saturday, November 19, 2016

Bombarding young mice with video and audio stimulation changes the way the brain develops. But some scientists think those sorts of brain changes could protect kids from stressing out in a busy world.


'Minibrains' Could Help Drug Discovery For Zika And For Alzheimer's

Sunday, November 13, 2016

Each lab-grown cluster of human cells fits on a pin's head, but contains some of the cell types and circuitry of a real brain. The structures already are offering insights into how Zika attacks.


Brain Implant Restores Sense Of Touch To Paralyzed Man

Thursday, October 13, 2016

A mind-controlled robotic arm has pressure sensors in each fingertip that send signals directly to a paralyzed man's brain. It's still experimental, but could eventually help thousands, engineers say.


Brain Game Claims Fail A Big Scientific Test

Monday, October 03, 2016

When a team of researchers evaluated the scientific literature on brain games, they found little evidence that the products improve memory or thinking in real-world tasks.


Rats That Reminisce May Lead To Better Tests For Alzheimer's Drugs

Thursday, September 29, 2016

Most potential Alzheimer's drugs are tested on mice. But rats may be a better choice because they seem to have a type of memory that's more like ours, and also are highly vulnerable to Alzheimer's.


War Studies Suggest A Concussion Leaves The Brain Vulnerable To PTSD

Monday, September 26, 2016

Troops returning from Iraq and Afghanistan are far more likely to develop post-traumatic stress disorder if they have suffered a concussion. The reason may be a change in the brain's fear circuits.


How A 'Sixth Sense' Helps Simone Biles Fly, And The Rest Of Us Walk

Wednesday, September 21, 2016

Scientists are finally beginning to understand proprioception, a sense that tells us where our body is in space. Much of what they've learned comes from two girls with a rare genetic disorder.


When Blind People Do Algebra, The Brain's Visual Areas Light Up

Monday, September 19, 2016

A study of 17 people who have been blind since birth found that areas of the brain usually devoted to visual information become active when a blind person is solving math problems.
